If you have defined additional pollers, and want to assign a poller to handle MIB graphing, edit the properties file.You must have created the poller that you want to use for MIB graphing before you edit the file.

To assign a poller for MIB graphing:

Open the following file: $TIPHOME/profiles/TIPProfile/etc/tnm/tnm.properties.

Change the value of the tnm.graph.poller parameter from DEFAULT_POLLER to the name of the required poller.

If a poller is not being used to monitor the network, you can remove the poller from the monitoring system.

To remove a poller from the monitoring system, you must delete its record from the NCMonitor Poller table, which removes the record from the Monitor Policy editor. The ncp_poller process attempts to remove the relevant record from the poller table and then exits.

Complete the following tasks to remove a poller from the monitoring system.

From the Network Manager server, issue the following command.

ncp_poller -deregister -domain [domain_name] -name [poller_name]

Note: When you issue this command, the record is deleted from the NCMONITOR Poller table.

From the Monitor Policy Editor, edit each active policy to use a valid poller.

TMR means Tivoli Management Region. It is a set of systems that are managed by one server. Each TME has its unique set of clients. Tivoli does not support more then one TMR at a particular time, but you can interconnect one or more TMRs.

Migration is used to move client files from one storage pool to the next storage pool in the storage hierarchy. Migration will make some empty space in disk pools which can be used for taking backup of the client machine.
